How to solve CTS Placement Papers?

Hi every one,
I want to share my interview experience @cogni pune yesterday.
Before that I wanna tell you that before we were sent to cognizant 4 d rounds. our extempo round was held by a consultancy through we got mails. nearly 1500 or more people were there and out of them 600 or so people were shortlisted and hall ticket and doc verification were done.

Talking about the experience in cognizant...Still 700 or more people were there(from other consultancies). There were 5 rounds.

The rounds went all he day 4m 8am..We were not sure whether GD was going on or Extempo..finally @11am my name was called...nearly 15 students in group were called inside..the person taking GD was very cool n calm.he told us to choose any topic by ourselves.the topic should not contain current issues,my role model,about yourself,my mom-dad,about politics,country..he told the topic must be something unique & interesting.& he would ask everyone to speak 4 abt 30sec on it.I chose the topic"Euthanasia".He was very impressed,n carefully listened 2 it. finally after everyone's turn results were announced n I was selected.

Tip4GD/Extempo:-Please have knowledge of current issues,go through unique gd topics..Discuss some few topics with your friend just 4 practicing purpose..speaking improves by it.

Interviewer: so u like drawing...wot kind of drawing do u draw??can u draw something 4 me in 5mins...
I: sure sir...drew..till den he was having a look at my resume...done with it

Interviewer: very good and very nice..
I: Thank you sir

Interviewer: OK shruti,actually the project 4 which vr hiring is mainly concerned with travelling 4m places 2 places n night shifts....are you comfortable for relocation and night shifts?(they check whether you are confident or not)..
I: I said yes for relocation but no for night shifts..

got rejected...the reason when I thought and came 2 know 4m my friend was I should have told yes 4 night shifts...they just check confidence n if at all we have security concern n say no 2 night shifts, then try 2 convince them in other manner how your best suitable 4 that job(I cud speak all dis in the time when he told me at last " anything u wanna ask me or say something about yourself..???")..dis he gave bcos he was expecting some words regarding job confirmation which i didnt understand n got rejected.Of course it was my 1st interview exp,n wud try it wud never happen again...so be confident...if at all u have any concerns or boundaries,say it clearly but convince him how suitable ur 4 dat job...4dis u need 2 speak up...
